It actually has 3 filters.  A simple dust catcher, a charcoal filter, and a
Hepa.  It's nice really, it's not an "Ozone Generator" although they do
admit the unit does produce a small amount  (I believe quite a few
electronic devices do, actually).

It's relatively new, so there aren't too many reviews yet.  It has helped in
reducing my cat's dander quite a bit, actually..

We shall see, I can respect your concerns for ozone..  I hope this model
doesn't appear on the blacklists.

One problem with this article that they make no destinction betweeen
two different devices:
1) ozone generator
2) electrostatic dust precipitator

Both devices have corona discharge in them, which generates a litle
ozone as by-product. But:
    Device 1) has ozone generation as primary goal,
while it does not have anough air-flow or precipitation surfaces to
remove particles from the are. So, they do not purify the air, and
yet produce ozone that is not something humans should be around. It is
extremely active gas that reacts with preaty much everything and so
modifies organic molecules. Even if there would not be medical evidence
of its harmfulness, it should be treated with precaution. So, if you
ask me, device 1 is counter-productive as it has possible harm and no merit.
    Device 2) (which, btw. Ionic Breeze claims to be) is specifically
designed to remove particles from the air by charging particles through
corona discharge flow, with subsequent attraction of charged particles
and deposition on a counter-electrode surface. Such devices are widely
used in undustry for air purification in high performance large
through-put units and are extremely effective, specialy for removing
small particles not caught by normal filters. So, devices 2 are in fact
comparable in efficiency and can be better then HEPA filters in removing
small particles. You have to check the specs and see 2 characteristics,
"Purification specs":
- air throughput
- particle deposition rate
when comparing different air purifiers.

So, there are 2 different issues there
- ozone generation that is possibly harmful
- purification efficiency
It can well be that particular (large) electrostatic dust precipitators
for home use have higher air throughput and particle desposition rate
than comparably priced HEPA air purifiers. And yet there is potential
harmfulness of ozone. It will be not a simple decision, as usual you
will have pro and cons. But for HEPA filter with same purifications
specs as electrostatic dust precipitator I would use the first because
of absent ozone.

Hi Pious,

Ionizers are to be avoided if you have asthma, because they can make your
condition worse.  Take a look at number 3 in their list of things to do to
protect your lungs:

and if you read through this, you'll see why:

Sorry - that's probably not what you wanted to hear, but if you have asthma,
those ion purifiers (there's an oxymoron!) are bad news.

So I've heard..

Fortunately, I do not have asthma, although I am rather environmentally
aware.  These units are apparently 'approved' by some sort of Asthma
Associations.. are these claims and/or groups who are approving them, all
bogus?

Again, this unit is *not* an ozone generator, per se, although they do admit
to trace amounts.. (which again quite a few electronic devices do)

I knew I was treading in dangerous waters here in regards to this
technology, thanks for the input, regardless. ;)
